A single web page application using AngularJS. It contains a form within a modal window that has validation. It also lists the people added via the form.
Given more time I would add a directive to search people/dates on the list, orderby, and pagination. It would also have a RemoteService Factory that fetches remote data sources and returns a promise.

| pd.unique(df.column_name.ravel()) | |
| # Convert Series datatype to numeric, getting rid of any non-numeric values | |

| df = df[df.column.isin(valuelist)] |
Spark is used for large-scale distributed data processing. It has become the go to standard for a lot of companies in the technology industry. The Spark framework is capable of computing at high speeds, processing massive amounts of resilient sets of data, and it does it all while computing in a highly distributed manner.
Jupyter Notebooks, commenly called "Jupyter", has been a popular application within the Data Science community for many years. It enables you to edit, run, and share Python code into a web view. It allows you to execute your code in a step by step process in order to share parts of your code in a very flexible way for data analysis work. This is why Jupyter is a great tool to prototype in, and should be used at all companies that are data centric.
Most data engineers argue that the Scala programming language version is more performant than Python version, and it is. Howev
